Abstract

In the Heumatt area (Zurich Seebach), three buildings of flats will be retrofitted (Hochhaus, Kurzhaus and Langhaus). In the framework of this project, a Central Solar Heating Plant with a Seasonal Stor-age (CSHPSS) is studied with the objective to halve the remaining heating demand. This report gives a synthesis of the main results obtained during the course of the Heumatt CSHPSS’s system analysis and study. The results are presented from the most recent to the early ones. The main objective of the study is to establish a dynamic model the whole system and simulate the thermal performances to optimally size the main components. The system design and control strategy is explained in chapter 2. Chapters 3 and 4 contain the CSHPSS design results and thermal performances of the variant “Hochhaus” and “Hochhaus + Kurz-haus” for a solar fraction of 50%. Thumb of rules are given in chapter 5, based on the two previous variants (chapter 3 and 4). Finally, chapter 6 presents the optimization results performed on the largest variant (Hochhaus + Kurzhaus + Langhaus). Sensitivities to some parameters are also shown.
